Pervious concrete technology is a special and reliable way of fulfilling increasing specifications for the climate. Pervious concrete is important in restoring groundwater, minimize erosion and converging flood water by absorbing rainwater and allowing it to seep through the land. Pervious concrete is comprised of coarse aggregate, Portland cement and chemical admixtures and is a building substance. It is somewhat different from standard concrete since there are little to no fine aggregates. The main objective of this project work is to study the densification and splitting tensile strength with the infiltration rate of pervious concrete. Also to do water quality test of rainwater after passing from 3 inches of the charcoal layer. The results concluded Compressive and splitting stability of Pervious concrete shows an extensive increment in strength when 2% of Ta titanium Dioxide is replaced by cement at the curing age of 7, 14 and 28 days. At 28 Days mean compressive and splitting tensile strength (Having Strength Enhancement Admixture) comes up to be 2104.5psi and 531.4 psi respectively which is considerable for Pervious concrete. From the infiltration rate test it can be concluded that as the percentage of gravel increases in the concrete mix, the permeability or infiltration rate increases. Infiltration rate ranges from 838.5 in/hr to 927.8 in/hr for the two concrete mixes M1 (1:0:2.5) and M2 (1:0:3) respectively. From the water quality test it can be concluded that when rainwater is passed from a 3inches layer of charcoal the PH value increase from 4.47 to 5.77 which can be used for cleaning and bathing in our houses. Hence it is recommended that 100% reduction of sand from concrete give significant mechanical strength and an increase of infiltration rate can be proposed for the roadway of parking and walking track. Also after passing rainwater from 3 inches layer it can be recommended for cleaning and Bathing Purposes.
